Stuxnet has already been linked to another virus, the Duqu data-stealing trojan, but Kaspersky’s research suggests the cyber weapons program that targeted Iran may be far more sophisticated than previously known.

Kaspersky’s director of global research & analysis, Costin Raiu, told Reuters on Wednesday that his team has gathered evidence that shows the same platform that was used to build Stuxnet and Duqu was also used to create at least three other pieces of malware.
